l BOLT Lock.

Application filed February 16, 1927, Seria1`No. 168,701, and in Germany .Tune 17, 1926.

My invention relates to slide .bolt locks for large doors such as used in storage rooms, railway-cars and the like, and consists in a slide-bolt carrying the lock proper that may at the same time serve as a handle for the bolt and it has particularly for its object to lock the slide-bolt as well the locking position as in the open position lwhich may in some cases be desirable. Further objects of my invention will appear from the following specification. Inthe accompanying drawing an embodiment of the invention is illustrated by way of example.

Fig. 1 is a device;

Fig. 2 shows a section through the slide bolt lock along line A-B of Fig. 1;

Fig. 3 illustrates the baseplate for the slide bolt in plan view; Figs. 4c and 5 show on an enlarged scale the bolt seen from below in the closed and open position, respectively,

front view of the looking the coverplate and annularflocking member from below;

Figs. 7 to 14a show various details; and Fig. 15 illustrates the key used (Figs. 9 to 15 being drawn on an enlarged scale).

On the door 1 there is fastened by means' of screws 1 a base-plate 2 for carrying a` slide-bolt 3. Said slide-bolt 3 is provided with a lockcasing 5 which serves as a handle. Longitudinal slots 6 are provided in the slide-bolt to receive bail-shaped guide elements 7 fastened to the door by means of screw bolts 8 having fiat T-shaped heads 9A (Fig. 8) which engage with or lit into corresponding holes of the side parts of the bail-shaped guide elements which extend through the slots 6. The screw bolts 8 eX- tend through holes in the base plate 2 Vand through holes of the door upon which the slide bolt is mounted and are fastened by means of nuts 10. In a similar manner the socket or keeper 12, with which the slide bolt engages in the locking position, is fastened by means of screw bolts 8 with flat T- shaped heads 9 and by means of nuts 10 on the fixed door frame 11. On the T-shaped heads 9 holding the socket or keeper a little square plate 13 is laterally fastened by soldering which covers vthe side opening of the T-shaped slot of the respective wall of the keeper and serves as a guide and at the same time as a stop for the bolt end entering into the keeper. Beneath the screw bolts 8 the respective parts of the door are providedwith washers 111 and 15 and between the frame 11 of the door and the keeper 12 a plate 17 is fastened by means of a screw 16 which is in alignment with and forms a continuation of the base plate 2 upon which the bolt mechanism is mounted. Y

The cylindrical lock casing 5 is integral with the bolt proper and constitutes together with the key 19 when put into the key-hole 18 a convenient handle for sliding the bolt into its keeper 12 or for withdrawing it therefrom. The lock is preferably of the well known type of cylinder lock, in

. ing 5; they are provided with springs 22 on Fig. 6 shows thelock after removal ofl their outer side by means 'of which theyr abut against the inner wall of the casing 5 (Fig. 6). On the inner side they are provided with pins 23 and 24' arranged oppol site to each other. The pins 23 of different combination elements are of different length so as to correspond to the respective steps vof the key-bit of a key 19 and extend through'ahole 25 of an element 26 (Fig. 10) into the keyhole 18 of cylinder 20. The element 26 partly serves as a 'bearing for the cylinder 20 partly as a guide lfor the surrounding combination elements 21 and is fastened to the bottom of the lock casing 5 byymeans of screws 27. The pins 241 engage a groove 28 of the element 26 and someof them are provided with a cylindrical projecting portion 29 which is adapted to engage bores 30 of element 26 as well as bores 31 of cylinder 20. When the pins 23engage the slot of the keyhole`18 the cylinder 20 tion 34 of' the annular bolt fastener the latter being again held against rotation. 0n the cylinder 2() an annularI bolt fastener 32 is fitted from below (Figs. d and i2) having a projection 33 on the inner ring face which engages a longitudinal groove oit the cylinder 20. Thus the bolt fastener will be moved with the cylinder 20 as soon as the latter is actuated by means oi' the hey. rlhe annular bolt fastener 32 moreover has two lateral extensions 34, 35 (Fig. l2) arranged at a right angle relatively to each Other. The extension 34 has an inclined upper face as shown in Fig. 13, while the ez;- tension 35 is provided with a di'nvnwardly projecting lug l/l. When the loch is in the open position projection 34- will occupy a` position (Fig. 5), in which its :fviscoincident with the longitudinal axis olv the slide-bolt 3. Vhen the loci; is closed projecv tion 35 will occupy this position (llig. a).

At the underside of the slide-bolt a recess is provided extending approximately from the middle of the bolt to the lock casing 5 and in this recess a spring controlled 1 locking bar 38 is pivotally mounted on a cross pin 37 and controlled by a spring which rests upon the base olf recess The bottom 'l ce of the locking` bar 33 is provided with a protruding step ll() and its end which extends towards the lock casing 5 terms a tongue 41 the lower face of which is inclined in the direction the lock is turned when actuated by the key. ln the open positicn el1 the lock the inclined upper face or' proyecbelow the inclined face of tongue 4 1 of vhe locking bar 38, the inclination oi" the upper lace of projection 341- corresponding to Vthe inclination of the lower face of the to fl-l. lllhe locking element is thereby against the action oi its spring recess 36 so that the step CO oi.' the loc bar 33 is 'aised above the upper tace el base-#plate 2 upon which the bolt slides. lbf the lock .is closed andv cylinder 2O to gether with the annular bolt fastener 32 is .rotated in 'the direction of the arrow liliggj. 1i) until its lng 44 meets tongue fil, the projection 34- wiil release the locking element 38 which under the action oi spring 39 is pressed down. According to the position the bolt at this nioment-whether it has been drawn back or pushed forward-the*protruding step 40 of the locking bar enters into one of the two holes l2 of base-plate 2 which are arranged over corresponding recesses 43 in the door l, and is held in this position by projection 35, which by the turning of the key has been moved, so that it is now bearing upon the upper ,tace of tongue 4l, thus preventing locking member 38 'from being moved back into recess 36.

The slide-bolt may thus be locked not only in the closedposition but also in the open position which may be el' advantage, it it is desired to prevent accidentel closing olE a door, 'for instance in a storage house or railv'ay car.

in some cases it may be convenient to arrange the'bolt in the lixed door frame and the izeeper in the movable door.
